Please note that this chain of events is in complete violation of the arrival testing rules and procedures that are published by the government, however most people accept it because it's very hard to get to a live person on the phone and explain to the PHAC that CBSA made a mistake and forgot to notify you of being selected. So in this case, you call the testing provider to ask that they send you a home test, and then you do the test in a video call, and send them the sample, and finally get the results. This usually takes 1-2 weeks.
